Clamp on Rod Holders for Outriggers?

[Whalecod]

I have a '90 GradyWhite Gulfstream with an original Hardtop. When I bought the boat it came with Lees Outriggers with flushmount hardtop Outrigger Holders. In time they have weakened and flex too much now to hold the outriggers. I have a few solutions in mind. One being to move the bases to the gunnel. The second being, leave them on the hardtop and reinforce them with backing plates via welding etc..( kinda ugly but would work) and the third option I thought might be to attach clamp on rod holders to the tube framing that supports the hardtop. I know the tube framing will hold them and I like the fact of not having to lower them down to gunnel height, but there is one question and one potential problem. The question is do you think the clamps will hold 15 foot Lee outriggers ( 1 to 1.5 inch in diameter outriggers) in place sturdy with a 4 bolt 316 stainless clamp? And as far as the problem goes, the clamp on rod holder is, well, just what it says...a clamp on rod holder meant for rods, not outriggers. It has a gimbal bottom that narrows right down to fit the bent butt of the outriggers but the problem is its too long by 3 inches. Solution? Have a machine shop saw off the top three inches? I think that'll prolly work. What do you guys think?
